| 3 | **Publisher:** Elsevier · **ISSN:** 0308-8146 · **Source:** [Guide for Authors](https://www.sciencedirect.com/journal/food-chemistry/publish/guide-for-authors) · **Verified:** 2026-07 (confirm exact limits at source before submission). |

| 5 | ## Aims & scope |
| 6 | Food Chemistry publishes original, rigorous **analytical/chemistry-driven** research on the chemistry of food: composition and structure, bioactive compounds, analysis and authentication, processing chemistry, food safety (chemical), and sensory-linked chemistry tied to identified compounds. The bar is **chemical insight from validated methods** — not descriptive screening. Studies must report validated methods, adequate controls, genuine replication, and defensible quantification. Scope-mismatched food-engineering or purely sensory work is desk-rejected. |

| 8 | ## Article types |
| 9 | Original Research Articles; Review Articles (usually invited or pre-proposed); Short Communications; Analytical Methods papers. Rapid, well-validated method papers are welcome. |
| 10 | |
| 11 | ## Manuscript structure |
| 12 | Title page → Abstract → Keywords → 1. Introduction → 2. Materials and methods → 3. Results and discussion → 4. Conclusions → (Declarations) → References → Figure/table legends. Use **continuous line numbering** and page numbers. |
| 13 | |
| 14 | - **Abstract:** unstructured, single paragraph, ~200 words (confirm; graphical abstract is separate). |
| 15 | - **Keywords:** up to 6. |
| 16 | - **Highlights (required):** a separate editable file, **3–5 bullets, each ≤85 characters** including spaces. |
| 17 | - **Graphical abstract (required):** one concise image submitted as a separate file, legible at Elsevier's display size. |
| 18 | |
| 19 | ## Reference style |
| 20 | **Elsevier numbered (Vancouver) style.** In-text citations are bracketed numbers `[1]`, `[2,3]`, numbered in order of appearance; the reference list is numbered in the same order. |
| 21 | |
| 22 | Example (journal article): |
| 23 | > [1] A.B. Author, C.D. Author, Title of the article, Food Chemistry 400 (2023) 133912. https://doi.org/10.1016/j.foodchem.2023.133912 |
| 24 | |
| 25 | ## Figures & tables |
| 26 | - Vector where possible (EPS/PDF); raster at **≥300 dpi** (line art ≥1000 dpi). TIFF/JPEG accepted. |
| 27 | - Fit one (~90 mm) or two (~190 mm) column widths; embed fonts; consistent, legible labels. |
| 28 | - Tables editable (not images); cite all figures/tables in order. |
| 29 | |
| 30 | ## Method-validation requirements (journal-specific) |
| 31 | Report linearity, LOD/LOQ, recovery, precision, and quantitative concentrations. Compound identification needs authentic standards or MS/MS confirmation (not library hits alone). Bioactivity claims must be backed by chemistry; chemometric models must be validated; avoid single-batch-only conclusions. |
